TOlVIIJI HIRAO, OF SAN JOSE, CALIFORNIA.

INK-BOTTLE.

To all whom it may concern:

Be it known that I, ToMIJI HIRAO, a subject of the Emperor of Japan,residing at San Jose, in the county of Santa Clara, State of California,have invented certaln new and useful Improvements in Ink-Bottles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention is directed to improvements in ink bottles, andhas for its object to provide a device of this character with means forfeeding ink to the pen.

A further object of the invention is to provide an ink bottle,constructed in such a manner that ink will be automatically fed to a cupin which the pen is dipped, and further to provide an ink bottle, whichwill afford a uniform depth of ink in the cup, thus insuring an equaldip for the penpoint.

A still further object of the invention is to provide an ink bottle,constructed in such a manner that the ink therein will not evaporate,and one which will exclude dust.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure 1 is a side elevation ofthe device. Fig. 2 is a vertical central sectional view through thesame. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is asimilar view on line H of Fig. 2.

Referring to the drawing 1 indicates the bottle, which is preferablyformed from glass, and is provided with the exteriorly threaded neck 2.Threaded upon the neck is a cap 3, said cap having mounted therein awasher 4, which is adapted to engage the upper edge of the neck, whenthe cap is in place.

Fitted in the neck 2, and at the lower end thereof is a disk 5, saiddisk having its periphery provided with vertical channels 6. The disk isfurther provided with a central aperture 7, the purpose of which willappear later.

Specification of Letters Patent.

Application filed August 20, 1915.

He into the tube 8.

Patented Dec. 28, 1915. Serial No. 46,540.

Secured in any suitable manner in the aperture 7 is the upper end of atube 8, which is tapered, as at 9. The lower end of the tube is providedwith a valve seat 10, and coacting with said seat is a ball valve 11,which normally engages said seat.

Slidable in the tube 8 is a tube 12, said tube being also tapered at itslower end, and is provided with a ball valve 13, which engages the seat1%. The upper end of the tube 12 is provided with a cup 15, which isformed by flaring the upper end of the tube. Since the tube 12 slideswithin the tube 8, it is obvious that the same acts as a piston, whichon its up stroke will unseat the valve 11, thus drawing ink from thebotl/Vhen the tube 12 is the valve 13 will unseat, thus permitting inkto enter the tube 12, said valve seating when the tube 12 movesupwardly, thus trapping the ink in said tube and cup 15.

Encircling the tube 12 is a rubber band 16, which has its lower endengaged with the upper end of the tube 8, and its upper edge engagedwith the tube 12, adjacent the cup 15, and since the band is formed fromrubber, it is obvious that the same will, when expanded, hold the tube12 in its raised position, it being of course understood that when thetube 12 is moved downwardly, the band will be compressed.

Should the tube 12 be moved downwardly too rapidly through carelessness,ink would tend to overflow from the cup 15, but should this happen, theink will pass through the channels 6 into the bottle.

When the pen is dipped into the cup 15, the tube 12 will be moveddownwardly, thereby transferring the ink from the tube 8 to the tube 12.Upon the up stroke of the tube 12, the valve 13 will be seated, and asthe tube 12 moves upwardly, the suction incident thereto will unseat thevalve 11, and draw ink into the tube 8.

What is claimed is 1. An ink bottle having an apertured disk mounted inthe neck thereof, a tube fixed in the aperture, a second tube slidablymounted in the first named tube, said tubes hav ing valves operable intheir lower ends, as and for the purpose set forth.

moved downwardly,

2. An ink bottle having an apertured disk mounted in the neck thereof, atube having its upper end fixed in the aperture and having its lower endprovided with a valve, a second tube slidably engaged in the first tube,and having a valve in its lower end, said second tube having a cupformed upon its upper end, a flexible band connecting the tube andserving to normally hold the second named tube in its raised pfiosition.

In testimony whereof, I a X my signature, in the presence of tvvoWitnesses.
